The Department of Defense, or DoD, launched ARPANET in 1969. The ARPANET was designed to allow defense researchers at various sites across the country to share scarce computer resources, communicate and collaborate. Most of the ARPANET locations were at universities involved in defense research. As you can see, the ARPANET was not designed with security in mind but was designed to promote openness and the sharing of information. The most popular use of the ARPANET was to send email. Additional features of the ARPANET included discussion groups, access to databases, and file transfer.
